axe repair/upgrade

[Mman]

I think it'd be great if miners could use a few crafted gold or iron to repair that axe that has 3% left. That way mining would be profitable for everyone and not just the rich ppl (or the ones that spent ages saving up) who could afford a diamond axe. It'd also be cool to use a diamond or 2 to improove your diamond axe and make it more powerful. Such as you lay down your diamond axe and a few diamonds, craft it as if it were money or a tool, and you get an axe that lets you mine faster.
